Title: Optical coupling structure for optical fiber and photodetector
Inventor: HORIMATSU TETSUO
IPC: G02B6/42
Filed: 1987-08-21
Abstract: PURPOSE:To assure a smaller size, wider frequency range and lower noise characteristic by forming a diffraction grating to the mid-point of a waveguide and projecting the guided light diffracted by the diffraction grating on a photodetector provided substantially in parallel with the waveguide. CONSTITUTION:The signal light transmitted via an optical fiber 1 is guided into the waveguide 2 provided on the exit light axis of the optical fiber 1 and the guided light of the waveguide 2 is separated from the progressing direction of the guided light at a prescribed diffraction angle in the diffraction grating 3 provided at the mid-point thereof and is emitted. The exit light can, therefore, be received in the photodetector 4 provided substantially in parallel with the waveguide 2, by which the incident direction of the signal light and the taking out direction of the electrical signal can be paralleled. The device is thereby miniaturized. Since the electrical interface of the photodetector 4 and the electrical circuit can be made horizontal, the inductance of the interface part is decreased and the wider frequency range and the lower noise characteristics are assured.

Abstract: PURPOSE:To aim at facilitating the programing of a working process from measured data obtained under profile copying operation, by connecting a profile copying control device to an automatic programing device to transfer the measured data from the control device to the programing device. CONSTITUTION:When a CPU34 delivers its profile copying operation starting instruction to a profile copying control device 2, a CPU delivers instructions indicating feed speeds for spindles to a profile copying operation control section 23 which feeds a table 10 at an instructed speed in the X direction, and as well which detects the displacements of a tracer head 12 in the axial directions and drives X-, Y- and Z-axis motors to have the resultant displacement thereof become a set value. Further, the head performs a profile copying operation, and the displacement data thereof are transmitted from the control section 23 to the CPU20 which therefore renews the content of a present position counter area for S, Y and Z axes in an RAM22 and which therefore, transfers the data of speed changes for the all axes, the present position and instruction speeds to an automatic programing device 3 at a predetermined cycle period. Further, the CPU34 programs an NC working process with the use of these input data, and delivers it to a floppy disk unit 33.

The encoder B rotates in synchronization with the crank shaft of pump system A and emits signals about the rotational angle. The signals shall serve in a control circuit C for opening or closing a solenoid valve D on the basis of ON/OFF control signals given externally for example, signals from a pressure switch, which senses the upper and lower limits of discharge pressure of this pump system A. Because opening and its releasing of suction valve is carried out through the action of a lifter rod device E, switching of the pump system A from the loaded to no-load operation and vice versa is performed quickly and stably.

Filed: 1984-10-05
Abstract: PURPOSE:To reduce misses of measurement by increasing the aperture ratio of an object which forms an optical path and decreasing depth of field, calculating the differential value of the brightness signal of a formed image, and comparing a distribution of points where the differential value exceeds a specific value. CONSTITUTION:Lenses 1 and 2 which form an environmental image on photosensor arrays 3 and 4 are held by a frame 5 and coupled together mechanically, and moved forth and back by a motor 5 as shown by an arrow 6. Then, the lenses 1 and 2 have large aperture ratios and are made relatively small in depth of field. The lenses 1 and 2 are moved by a moving means 28 for focusing and synchronized with a driving circuit 5 for the photosensors 3 and 4 so that a time period longer than, for example, a distance calculation time is obtained. An output image signal is differentiated by differentiation circuits 6 and 7 with time and a distribution of points where the differential value exceeds the specific value is compared. Consequently, the distance distribution is measured within a practical time and misses of measurements resulting from an erroneous assumption of corresponding points of a right and left images are reduced greatly.

Abstract: PURPOSE:To maintain a constant degree of heating of water and steam in a furnace and an economizer even in the case that fuel of different characteristics is used by seeking the rate of the total received quantities of heat for economizer and furnace to the total received quantity of heat for the whole boiler and by correcting the spray flow rate based on the ratio of the received quantities of heat. CONSTITUTION:Based on detection signals 25-28 from heat sensors 21-24 of a boiler 1, the rate of the total received quantities of heat for an economizer 7 and a furnace 2 to the total received quantity of heat of the whole boiler 1 is sought by a calculator 29.

When the degree of opening of the spray flow rate regulating valve 17 is regulated by taking the spray flow rate as the spray flow rate instruction 32, the water or steam that flows to the side of the economizer 7 and the furnace 2 is increased or decreased according to the increase and decrease of the spray flow rate so that the degree of heating of the water or steam in the furnace 2 is maintained constant even if the rate of the received quantities of heat of the economizer 7 and the furnace 2 vary according to the characteristics of the fuel.
